This invention relates to certain new and useful improvements in flue caps for gas stoves and relating to that class of devices for extracting and consuming soot and grease from the heating gases escaping from oven compartments or heating chambers and other .areas around a gas stove, has for its primary object to mount a flue cap upon a laterally positioned flue outlet for a gas stove and to direct heated gases through a grille or perforated area in the rear wall or back strip of a gas stove to discharge such gases into a room in a direction away from the adjacent room wall.

A further object of the invention is to provide a flue cap attachment for gas stoves assembled thereon in the manner above stated and to provide an arched hood or bafile of the stove backing strip overlying the grille or perforated area for'the outlet of gases to direct them forwardly of the stove and away from the adjacent room wall.

i A. still further object of the invention is to provide a flue ca attachment for gas stoves in which the out etend of the.fiue ca aligns with a perforated area formed in t e back .wall of the gas stove above the open burner top and below an upper shaft, the two outlets of the pipe extending over the heating chamher to a point rearwardly of the back wall of the stove burner top.

With the above and other objects in view that will become apparent as the nature of the invention is better understood. the same consists in the novel form, combination and arran ement of parts hereinafter more fully descri d, shown in the accompanying drawin and claimed.

11 the drawing Fi re 1 is a fragmentary front elevational iriew of a as stove having the flue outlet for the oven eating area disposed at the rear side of the stove with the flue cap mounted on the flue outlet elbow, and having its 3 open u per and directed toward a hooded perfora area in the stove backing at the up- P edge o Figure 2 is an enlarged detail view, partly showing e mounted flue cap for in section taken on hne 2-2of Figure 1,;

heat and gases from the flue outlet and forwardly through the perforated area in a backing strip;

Figure 3 is a fragmentary'enlarged front elevational view showing the perforated portion of the backing strip, the open upper end of the flue cap facing the same and the lower cut away edge of the backing strip beneath the overlying hood; and

Figure l is a fragmentary front elevational so view showing the burner top section of the gas stove with the flue pipe extension from the oven flue outlet having a cap flue thereon outletting through an area of perforations in the back wall of the burner section of the stove. v

The invention relates to a flue cap attachment for gas stoves of the type having an oven flue outlet in the rear wall thereof and said flue cap is adapted to be associated with the flue outlet in a manner for directin the heated gases in a direction forwardly o the stove, either through the stove backing strip above the oven or through the front wall of the stove above the burner top section for directing the heated gases escaping from the stove through the flue outlet in a direction to ward the center of the room and away from the room wall. In the form of the invention. illustrated in Figures 1 to 3 the flue cap is disposed between the flue outlet and the stove backing strip, while in Figure 4, the flue cap is carried by an extension pipe leadin from the flue outlet for discharging the sated gases through a perforated area formed in the back wall of the stove above the burner top.

As illustrated, the gas stove 1 is provided with an oven section 2 threaded into the stove casing, comprisin the rear wall 3 and top wall 4 and space therefrom to rovide an oven heating compartment 5, while the top of the stove 1 above the rear wall 3 is provided with the usual upstanding backing strip 6. The gas stove 1 further comprises a burner top section 7 a rear wall section 8 and an upper overhanging shelf .9, the backi'ngstrip 6 extending completely across the rear wall sections 3 and 8 as indicated in Figans 1 and 4.

' tion of the stove, the horizontal open up r end of the elbow flue outlet being provi ed with an inwardly directed shoulder or flange 11 for suppIorting a flue cap as shown in hood 13 at its up Fi re 1. he flue ca comprises a tubular co ar 12 having an e arged curved head or r end with an 0 en side directed toward t e rear face of the ackin strip 6 and lying juxtaposed to the strip an may be secured thereto in any suitable manher. If desired, steel wool or metal gauze ma be inserted in the flue cap to extract soot and greases from heated gases flowing therethrough.

An arched hood-14 is carried by the front face of the backing strip 6 and is of substantially semi-circular formation in front elevation, the forward edge of the hood 14 inclining or tapering from its up er edge of greater width'toward the lower ge of the backing strip 6 as shown more clearly by the reference numeral 15 in Fi e 2. The backing strip 6 within the hoo 14 is longitudinally cut away adjacent the stove top 4 between opposite sides of the hoodtend to provide a bottom slot 17, while the remaining portion of the backing strip 6 within the hood 14 is perforated as at 18 over its entire area, this perforated part of the backing strip and the slot 17 spacing the open side of the flue cap hood 13. The heated gases esca ing from the compartment 5 surrounding t e oven 2 flow throu h the flue outlet elbow 10 and enter the ue cap for final discharge forwardly of the stove 1 through the slotted opening 17 and perforations 18, the heated gases being discharged in a-direction toward the center of the room and away from the room wall. As above stated, any material, if desired, may be inserted in the flue cap for the extraction of soot and greases from the heated gases before discharge into the room.

In the form of the invention shown in Figure 4, the dischar e outlet for the heated gases from the oven eating compartment 5 is through the back wall 8 rearwardly of the 7, the pipe section 19 exopen burner to tending from t e flue outlet 10 and having an elbow 10 upon its end to su port the flue cap. The open side of the no cap hood faces the back wall section 8 and that portion of said wall aligned with the flue cap hood is provided with a plurality of perforations '18 permitting the flow of discharge gases through the wall section 8. The overhanging shelf 9 of the stove constitutes a baflle or a hood erformin the function of the hood 14 as s own in igures 1 to 3 for further deflection of the escaping gases to direct them away from'the adjacent room wall.

The above arrangement of flue caps is especially designed for association with gas stoves havin theoven flue outlet-in the rear wall thereo and directs the heated gases outlettingfrom the oven heating area in a direction forwardly of the stove and away from the room wall, it having been found practical to prepare thebacking strip 6 as above described to accommodate passage of the heated gases therethrough and also to construct the rear wall section 8 adjacent the open burner top 7 as described for the passage of heated gases. It will also be possible to dispose the open side of the hood 13 of the flue cap above the backing strip 6 for iorwardly directing the heated gases.

While there are herein shown and described the preferred embodiments of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
